My bet is on a flavoring in the new juice. I thought I had a PG intolerance but turns out to be a sensitivity to certain juices which must be from the favoring they use. I can vape 50/50 of some juices with no problems at all, others either the same day or the next morning my eyes are puffy and itchy like I have terrible hay fever. I tend to try and stay a little higher on the VG scale as I know I am a little sensitive to PG but, for me, it really has to do more with the flavorings. Some just don't agree with me.
Hang in there, you'll find a replacement juice that does it for you. Sounds like you are vaping a plain bacco juice, personally I like the Dekang and Hangsen juices (same company, different brand labels) for general inexpensive bacco. None have ever given me a problem but again YMMV.
